GEARED LOCOIJIOTIVE.

Application filed March 11, 1915.

To all whom it may concern Be it known that we, SAMUEL M. VAU- CLAIN and KENNETH RUsrIToN, citizens of the United States, and residents of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented certain Improvements in Geared Locomotives, of which the following is a specification.

Our invention relates to certain improvements in geared locomotives, z. 6., a locomotive in which the driving wheels are geared to a driven shaft.

One object of our invention is to construct a locomotive of this type so that the driving shaft and the gearing are accessible at the side of the locomotive, and the necessary repairs can be made without dismantling the locomotive.

A further object of the invention is to locate the locomotive driving shaft at one side of the locomotive and to locate the gearing between the driving shaft of each truck and the axles on the opposite side of the leconiotive.

A still further object of the invention is to provide means whereby the trucks can swing under the frame without disengaging the gearing.

These objects we attain in the following manner, reference being had to the accompanying drawings, in which Figure 1, is a side view of our improved geared locomotive; Fig. 2, is a sectional plan view showing the trucks and the longitudinal driving shaft and engines; Fig. 3, is a transverse section on the line a-a, Fig. 2; Fig. 4;, is a transverse sectional view on the line b7), Fig. 2; Fig. 5, is an enlarged side view of one of the trucks; Fig. 6, is a longitudinal sectional view on the line 00, Fig. and Fig. 7, is a sectional view of that portion of the driving shaft between the locomotive and the tender.

Referring to the drawings, 1 is the frame of the locomotive consisting of side plates 2 extending the full length of the locomotive and transverse plates 3 and 4. The transverse plates 4 are spaced apart and the frame 5 of the engine is secured to these plates, as clearly shown in Fig. 2. The engine is arranged transversely and extends the full width of the locomotive, in the present instance, directly in front of the fire box structure 6 of the boiler 7 occupying the space Specification of Letters Eatent.

between the front end of the fire box and the ash pit and a truck 8.

9 is the rear truck and 10 is the tender truck.

11 is the longitudinal driving shaft of the engine extending practically the full length thereof and having a crank section 12. This shaft is adapted to bearings 13 on the engine frame 5 and the shaft is also mounted in suitable bearings 14 at the truck. The shaft is made in sections and couplings 15 are used to connect the several sections. The coupling section 16 between the locomotive and the tender consists of two parts, the part 17 sliding in the part 18, and these parts are connected by universal joints 19 to the main portions of the shaft so that, while the engine shaft is driven, the portion of the shaft carried by the tender can accommodate itself to the movement of the tender which is coupled at 20 to the locomotive.

In the present instance there are three cylinders 21 mounted on the engine frame, and these cylinders are located on the opposite side of the locomotive from the driving shaft. The parts which need attention are readily accessible from either side of the locomotive. Steam is supplied to the three cylinders through the steam supply pipe 22, which is coupled to the steam chests of the engine, as clearly illustrated in Fig. l.

23 is an exhaust pipe for the engine leading to the smoke box 2 1 at the forward end of the locomotive.

The three trucks 8, 9 and 10 are identical in construction, in the present instance, and depending from the frame of the locomotive is a center bearing structure 25 having a center bearing 26 and fitting the cavity in the cross member 27 of the frame 28 of the truck and connected to the truck by a king bolt 29. The cross member is rigidly attached to the side frame 30 of the truck and springs 48 are also mounted on the truck together with the equalizing bars 19 which rest on the axle boxes thereof in the ordinary manner.

Mounted at one end of the truck is a frame consisting of two plates 31 spaced apart, and this frame is carried by the axles. In the upper portion of the frame is a hearing 32 for the section 33 of the transverse shaft 34 which, in the present instance, is made in three sections 33, 35 and 36. The

section 35 is connected to the section 33 by a universal joint 37 and is connected to the section 36 of the shaft by a universal joint 38. This joint .not only allows for the universal movement of the section 33, but also allows a limited amount of longitudinal movement so as to accommodate the turning of the truck on its pivot. The section 36 of the shaft 3 1 ismounted in bearings 39 secured to the transverse member 3 of the frame of the locomotive and has, at its outer end, a bevel gear Wheel 40 which gears with a bevel wheel 41 011 the shaft 11. On the section 33 of theshaft 34: is a gear wheel 42.

which meshes with intermediate gear wheels 43 on studs 44: mounted in the plates 31, and these intermediate gear wheels mesh, in turn, with gear wheels 4L5 secured to the axles 46 of the truck. These axles are mounted in suitable boxes 4-7 and have a certain amount of vertical movement in the frame of the truck. By making the shaft 34in sections connected together by universal joints, this movement can be accommodated without disturbing the relation of the gearing on the truck or the gearing on the main frame of the locomotive. Thus it will be seen that eachof the axles of the several trucks is positively driven from the main longitudinal driving shafts and, owing to the special construction, each truck is free to turn on its pivot and the trucks can be spring supported on the axles.

The engine frame is so designed that the engine can be assembled complete and mounted in its proper position. The location of this engine is directly in front of the firebox and the construction of the locomotive allows sufiicient room so that access can be had to all portions of the engine.

The side plates 2 are so designed that they inclose the working parts of the engine and also act as a shield for the upper portions of the gearing of the truck. 1 This gearing may be provided with guards of any suitable type so as to prevent accident due to carelessness when working around the locomotive. i

In some instances, instead of gearing, drive chains may be used for connecting the truck driving shaft with the axles, without departing from the essential features of the invention.
